as other have already said, Xmpp.js works quite well If it's Javascript it's already cross platform > Ye, which problem exactly? communicating via XMPP in a standardized way > All of them are solved partially And a new protocol based on half backed technologies would change that, how exactly? > On your platform you have a username and you are supposed to communicate with others with your username. On any forum or BBS I've been part of in my life, I've always used a nick, that changed over time. > Well, because XMPP standard supports nickname changing, which means in a context of a platform it would allow nickname spoofing. That's a feature, not a bug. In 1995 I could change my nick on IRC, in 1997 I could change my nick on ICQ, I still can change nick on Skype today (my artists friends do it on facebook all the times) Anyway, nick spoofing on XMPP is hardly a problem and it's not an XMPP fault. Have you ever tried to search for "someone has been impersonating me with FB messenger" on a search engine? > "Solved problem" of course. XMPP it's a solved problem, your chat where nick cannot be changed is your problem. Every implementation of standard protocols requires work, HTTP is a solved problem, but edge cases still exist. Name one standard federated protocol that could help you with that and make it simpler, please. Because I don't know any.
